Sharing the process of implementing the happy Xiaoxiaole algorithm in PHP

Happy Xiaoxiaole should be familiar to everyone. The following article mainly introduces you to the relevant information on how to use PHP to implement the Happy Xiaoxiaole algorithm. The requirements and sample codes are introduced in great detail. , it has certain reference learning value for everyone’s study or work. Friends who need it can follow the editor to learn together.

Preface

This article mainly introduces how PHP implements the happy Xiaoxiaole algorithm that we all know, and shares it for your reference. Learning, I won’t say much more below, let’s take a look at the detailed introduction.

1. Requirement description:

1. Randomly appear 5 colors in an 8*8 matrix square Color blocks.

2. When three or more color blocks are connected horizontally or vertically, eliminate these color blocks.

3. After the color blocks are eliminated, the upper color blocks move downward, and random colored color blocks fall down to fill the matrix vacancies.

4. Repeat steps 2 and 3.

5. Eliminating 3 blocks of the same color adds 10 points, 4 adds 15 points, 5 adds 20 points, 6 adds 30 points, 7 adds 40 points, and 8 adds 70 points , 9 points will add 100 points, 10 points will add 150 points, and each additional one will add 50 points more than the previous one.

2. The above code
